Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3658, here are decompositions:

41 + 3617 = 3658
101 + 3557 = 3658
131 + 3527 = 3658
167 + 3491 = 3658
191 + 3467 = 3658
197 + 3461 = 3658
251 + 3407 = 3658
269 + 3389 = 3658

Showing the first eight; more decompositions exist.
